MEASURING INSTRUMENT.

Specification of Letters Patent.

Patented June 10, 191 3.

Application filed August 5, 1907. Serial No. 387,144.

-; particularly in that class of such instruments of which the device shown and claimed in my co-pending patent application. Serial No. 322,709, filed June 21, 1906, is a type, wherein pendulum balancing or measuring means supported upon a shifting fulcrum are provided, and the object of the invention is to provide an instrument of this general character havin a novel and im proved construction and arrangement of such balancing or measuring mechanism, whereby increased strength and simplicity of construction are attained, together with reliability and accuracy of operation. and lessened liability of deterioration and derangement during use.

The invention consists, in part in a. measuring instrument of the pendulum type having two members, one of which is a pendulating weighted lever, and the other of which is a fulcrum support around which said lever is adapted for rocking movement during the measuring operation. wherein one of such members has a curved surfaced part supported for turning movement and adapted for rolling contact upon the other member for the efl'ective support of the lever in relation to said fulcrum support with a minimum of frictional loss due to surface inequalities or to shifting of the point of support of the lever during its rocking movements.

Another feature of impr vement comprised within the present invention resides in the employment, in connection with a measuring instrument of the pendulum type, of means whereby the suspending device for the pendulating weighted lever is preserved from being bound between the lever and its fulcrum support and is therebv relieved from the strains which would otherwise be imposed upon it.

The invention further consists in a measuring instrument of the character above set forth wherein the means for preventing binding of the suspending device between the lever and its fulcrum support includes similar separately formed disk like members interposed between the lever'and its fulcrum support in spaced relation, so as to support. the lever during its rocking movements with a minimum of friction and to facilitate and simplify the construction and assembling of the parts.

The invention also contemplates certain novel features of the construction, and combinations and'arrangements of the several parts of the improved measuring instrument, whereby certain important advantages are attained, and the instrument is rendered simpler, less expensive and otherwise better adapted and more convenient for use. all as Will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims.

In order that my improvements may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure l is a vertical section taken through the instrument in the broken plane indicated by the line a--a in Fig. 2; Fig. 2 is a partial sectional plan view taken through the improved measuring instrument in the plane indicated by the line b-J; in Fig. 4; Fig. 3 is a fragn'ientary sectional detail view showing certain features of the measuring mechanism to be hereinafter referred to; and Fig. 4 is a vertical section taken through the instrument in a plane at right angles to the plane of the section in Fig. i. and showing the measuring or balancing mechanism in front elevation.

in these views, wherein I have illustrated my invention embodied in a measuring instrument of the pendulum typo shown and claimed in my (impending patent application. Serial No. 767,761, the instrument is provided with a base frame 1 apertured at its lower part as seen at 2 for, the passage of a vertically directed draft rod 3, which is adapted to be connected with the load supporting member of the instrument. in any preferred way in such a way that a strain ("Hilll'lQHSHlfttL with the load may be transmitted to the measuring or balancing mechanism to operate the same. The load receiving member may be a pan, platform or equivalent device, which I have not considered it essential. to illustrate herein.

At the upper end of the draft rod 3 is a flattened part 20 provided with a clamping plate 21, secured by screws or otherwise in such a manner as to permitof securely clamping and holding between said parts 20 and 21 the lower end portions of steel or other flexible tapes or bands 22, the upper end portions 23 of which are upwardly ex tended in the casing 4 and are gradually divergent From each other. being carried over the outer surfaces oi revcrselv curved arms or extensions 2-1, 2t forming parts of pendulating levers, the structure and operation of which is, in the main. similar to the structure and operation of the correspondinr, part-s shown and claimed in my before-mentioned (impending patent application, Serial No. 767,761. As shown herein, there at" two of these levers, although but one, or any desired number of them may be employed without departure from my invent-ion, and said levers have downwardly extended parts 25 \vhereon the ends of the tapes or bands 29 are secured by clamping plates 26 held by screws or the like to the said levers in posis tion for secure clamping engagement over the'extremities of said bands or tapes. The lower ends of the downwardly extended parts 25, 25 of said pendulating levers also carry weights 27, 27 and adjacent to each such weight there is secured, as shown at 30, the lower end which is also for upper part extended around a curved bcaring surface produced upon a part or block 32, to the upper part of which the upper end of said flexible suspender is secured by means ot a transverse clamping strip 33 in such a manner as to sustain the pendulating lever etl'ectivclv in relation to the bearing block or part 32 so that the lever may swing or rock 't'reely around said hearing block or part during the measuring operation.

34 represents an auxiliary fulcrum supporting frame or extension of the base frame 1 within the casing or housing 4, the opposite sides'whereof are recessed at their lower parts as seen at 35 to afford spaces to receive the weights 27, 27 of the pendulating levers when the same are inactive, and at their upper parts the said opposite sides of the auxiliary frame or extension are notched out to pro vide seats for the angular ends 36 of the bearing blocks or parts .32, being provided, as set forth in said copending application Serial No. 767,761, with portions 37 which overhang said notched out portions and beneath which said angular ends of the bearing blocks or parts 32 are held by means of screws 38 in such a way as to prevent. their dislodgment and to brace and strengthen the upper part of the auxiliary frame while permitting ready withdrawal of said bearing blocks 32 or their ready insertion within the seats during the assembling of the'instrument.

The angular ends 36 oftherespective bearing blocks or parts 32 according to my present invention carry alined trunnions 39 axially arranged with respect to the curved surfaces of said parts or blocks 32 and on said trunnions 39 are held by means of nuts 40, fulcrum disks or parts 41. 41, similar to one another, but having radii greater than those of the curved surfaces of the blocks or parts whereon the suspenders 31 contact, the said fulcrum disks or parts 41 being capable of turning movement upon their trunnions 39 in the construction herein shown, and having their perimeters adapted to engaged and traversed by the opposite edge portions of fiat track like surfaces 29 pro-, duced upon the 'tions 25 of the pendulating levers, whereby said levers are effectively supported upon said rotatable disks or parts 41 for rocking or swinging movement around their respee; tive blocks or parts 3 during the measun: ing operation. rangement of the parts it will be seen that when a load is applied to the load support-- (not shown) a downward draft \Vlll be exerted upon the tapes or bands 22, be transmitted thereby to the reversely curved upper parts or extensions 94 of the wndulating lovers in such a manner as to cause said levers to swing outward in opposite directions and away from each other, whereby their tlat track-like surfaces ..9, 29 are caused to travel aroundthe perimeters ol the rotatable lulirum' disks or parts 41 by reason of the connection of the suspenders 31 with the bearing blocks 32.

my above-recited patent applicatit/n Serial No. 767,761, in this operat ing instrument the shifting of the fulcra for the levers affords a gradual ldngthening of the weighted lower ends thereof such as is calculated to increase very materially the capacity of the instrlunent, while at the 'same time the )eculiar nature of the connections of the draft devices with the upper ends of the levers assures the gradual shortening of said upper ends of the levers multanceusly with the lengthening of their weighted lower ends, so as further to augment the measuring capacity of the instrument, and the levers being normally pendout when in inactive position and wing horizontal during the measuring operation, it is apparent that the shifting of the t'ulcra for said levers upwardly around the curved upper surfaces of the fultrum disks or parts 41, 41 assures the support of thesaid levers downwardly extended p0r-.'
